Has Einstein Been Proven Right—Again?

Rumours have begun to circulate in the physics community that a group of scientists in the US have detected gravitational waves.

Their existence was predicted in 1916 Albert Einstein as a part of his general theory of relativity, but they have so far eluded scientists.

According to the theory, gravitational waves are ripples in the curvature of space-time that propagate outwards from their source—thought to be extremely violent events like the collision of two black holes.

According Lawrence Krauss, a cosmologist at Arizona State university, if the waves are discovered they could allow astronomers to observe the universe in an entirely new way.

“We could have a new window on the universe” he said.

The rumours centre on an experiment called the “Advanced Laser Interferometer Gravitational-Wave Observatory” (Ligo) which uses detectors in a number of locations across the United States to look for ripples in space-time.

Scientists on the Ligo team are thought to be in the process of writing a paper on their findings, though this has not been confirmed.

Kraus says he is 60% sure the rumours are true, but insists that he would like to see the data before he draws any more serious conclusions.
